II) NUMERICAL REPRESENTATION OF THE BAR GRAPH
The bar graph displays the columns sequentially from “0” to “6” until all columns
are showing. Then they are hidden again, and the sequential display is repeated. It is
possible to read each column one at a time, simultaneously displaying the numeric
measurement for that column above the bar graph. For example, the weekly rainfall
total from 3 weeks ago may be viewed. Also, the numeric data from each column
will correspond to the preveouly selected history (“DAILY,” “WEEKLY,” or
“MONTHLY”). To view individual totals from the last six periods:
1. Hold down the HISTORY/+ button for 2 seconds. The numeric data from
column “0” should appear at the top of the LCD screen, with the
“RAINFALL” icon displayed above the data.
2. Press the HISTORY/+ button again, column “1” will be highlighted, and the
numeric data will be displayed above the bar graph.
3. Continue to press the HISTORY/+ button until the data from each column (0
through 6) has been displayed.
4. Pressing the HISTORY/+ button once more, after viewing the data from
column 6, will exit this mode—returning to normal operation.
III) MANUAL RESET OF THE RAIN MULTIPLICATOR
Note: The rain multiplicator is the amount of rain needed to tip the teeter-totter
bucket (inside the rain gauge). The multiplicator is preset to a value of “105”
(0.0105 inches per tip); this number produces the most accurate rainfall
measurement. There is no need to manually set this number unless it has been
changed.
1. Remove the batteries and wait 30 seconds. This will reset the 1-hour
rainfall total, but the bar graph and other totals will remain.
2. Checking the polarity, install batteries.
3. During the brief 2 seconds that the LCD screen lights up, hold down the
HISTORY/+ button, until “105” appears in the LCD (the “5” will be
flashing).
4. If the multiplicator is not 105; use the HISTORY/+ button to to change the
last digit to a 5. Press the RAIN/SET button to confirm and shift to the
middle digit.
5. Press the HISTORY/+ button to change the middle digit, and press the
RAIN/SET button to confirm and shift to the first digit. Repeat process for
the first digit.
6. Press the RAIN/SET button to exit the Rain Multiplicator mode, and to enter
the normal mode. Follow Program Mode for set-up proceedures.
